Familiarity: I've put it through the wringer
Bought this for riding my bike on my trainer. It's super easy to attach to the bike and connect to my Garmin Forerunner 235. Connects automatically after initial set up. Only problem is that the construction feels a bit cheap and has the potential to fall apart. However, so far so good.
